Sienna Miller Raises the Bar on Brit-Girl Waves

The secret behind Sienna Miller’s perfectly imperfect Brit-girl waves, which at once suggest both a masterful styling routine and a laissez-faire approach, may remain a mystery—but the actress’s slightly more polished iteration of her signature look in New York City yesterday offered a few clues.

Falling into thick, bendy pieces too sleek to be the result of a lucky air dry, Miller’s blonde layers at the Tribeca Chanel Women’s Filmmaker Program’s annual luncheon had all the markers of a salon blowout and capable hands yielding a curling iron. Still, the style felt instantly lived-in thanks to a few random strands tucked behind her ears—while the blustery weather outside promised to deliver a final blast of wispy texture.
